# Objective

- Report V4 edit prediction patch apply failures as cloud rejection
events.
- Closes EP-210

## Solution

- Added `PatchApplyFailed` as an edit prediction rejection reason.
- Converted `prediction_edits_for_single_file_diff` errors into rejected
prediction results so the existing rejection pipeline posts them to
`/predict_edits/reject`.
- Kept interpolation failures reported as `InterpolateFailed`.

## Testing

- Ran `cargo fmt --check && cargo check -p edit_prediction`.
